Projects and circuits
All reasonable precautions are taken to ensure that the advice and
data given to readers is reliable. We cannot, however, guarantee
it and we cannot accept legal responsibility for it.
A number of projects and circuits published in Practical Electronics
employ voltages that can be lethal. You should not build, test,
modify or renovate any item of mains-powered equipment unless
you fully understand the safety aspects involved and you use an
RCD (GFCI) adaptor.
Component supplies
We do not supply electronic components or kits for building the
projects featured, these can be supplied by advertisers. We
advise readers to check that all parts are still available before
commencing any project in a back-dated issue.

What will you build this winter?
By the time you read this, British Summer Time – or your local
variant – will be over, the clocks will have gone back and the
nights will get longer and chillier for nearly three months as we
run into Christmas and winter. What to do as the weather turns?
Electronics of course!
Now is the perfect time to look back over recent issues, see what
projects you didn’t have time to start and settle down with a PCB,
parts and a soldering iron.
2021 – a great year for projects
We’ve had some really impressive projects this year, we
have PCBs for all of them and while the vagaries of silicon’s
international supply chains are impossible to guarantee, a quick
check shows that all parts are available, even if you sometimes
have to hunt a little harder. Just to get the ball rolling, here are a
few of my favourites.
If audio is your thing, then you should definitely try using
Nutube’s low-voltage valve technology in our pre-amplifier or
guitar effects pedal projects from the January and March editions.
How about a sophisticated DIY Solder Reflow Oven with built-in PID
control, which we ran in April and May? Or maybe the very handy
Touchscreen Wide-range RCL Box – just the thing for tinkerers who
like to run a lot of test with a variety of passive components.
For model railway enthusiasts, the Complete Arduino DCC
Controller (January) was very well received.
Maybe you’re a beginner. The Night Keeper Lighthouse
(September) and this month’s Door Alarm are both a satisfying
route to getting started with real electronic circuits.
We know that PICs is a hugely popular topic with many of
you, so if you’ve been meaning to really get to grips with this
important area of digital control then why not take the plunge
and build Mike Hibbett’s current PIC ‘n Mix project – the PIC18F
Development Board.
Christmas inspiration
Last, but not least, if you’re being pestered for Christmas present
ideas then why not give your nearest and dearest a gentle
hint about our range of PCBs – or better still, a subscription to
Practical Electronics (digital or print)!
Keep well everyone
